The lathe and mill are a perk of my current job.

Another year or so, and I might be able to get tolerance +/- .0001

Right now, I'm usually good with a thou.

Had an interesting issue with the crossfeed on the lathe. I got tired of measuring after every cut. So, I calculated inch to mills, ( everything is metric at work) and made a few cuts using the verneer dial on the lathe... And botched the part.

Now for the punch line: the dial WAS in mills.

Dam. More practice needed.
